+ *
+ * This class reduces the complexity of controller components which would

+ *
+ * The template class monitors mode and health state of its children
+ * and checks availability of devices on every detected change.
+ * AssemblyBase does not implement any redundancy logic by itself, but provides
+ * adaptation points for implementations to do so. Since most monitoring
+ * activities rely on mode and health state only and are therefore
+ * generic, it is sufficient for subclasses to provide:
+ *
+ * 1. check logic when active-> checkChildrenStateOn
+ * 2. transition logic to change the mode -> commandChildren
